LOOM.

SPECIFICATION forming part of Letters Patent No. 571,956, dated November 24, 1896.

Application filed January 3l, 1895. Serial No. 536,810. (No model.)

To all whom t may concern:

Be it known that I, EDWARD POEHNERT, a citizen of the United States of America, residing` at Rockville, in the county of Tolland and State of Connecticut, haveinvented a certain new and useful Improvement in Looms, of which the following is a description, reference beinghad to the accompanyingdrawin gs, wherein- Figure l is a front View of those parts of a loom to which my improvement particularly pertains. Fig. 2vis a top view of such parts. Fig. 3 is a view of the saine parts in vertical section on the plane cc The obj ect and purpose of the improvement is the prevention of injury to the parts of the loom and to the cloth which is being woven therein if a shuttle or other obstacle is caught accidentally between the reed and the warpshed in the beating-up motion of the lay.

The drawings show only the pertinent parts of the loom.

The letter CL denotes the lay as a whole, which has in practice the ordinary reciproeating or vibratory motion, and b denotes the reed. The reed is not fast in the lay, as is the more common practice, but its upper edge is rather loosely seated in the groove c, formed in the under side of the cross-piece which connects the two Vertical arms of the lay. The lower edge of the reed is held in place between the cross-piece d and the reed-confiner e. The reed-continer e is in a general sense a roll with trunnions at the ends journaled in the upright arms of the lay and having some rotary motion. The reed-conner is held in a position to confine the lower edge of the reed between it and the cross-piece d by means of the reed-conner spring f; but, so far as the action of the spring j' is concerned, if the reed in its beating-up motion strikes a shuttle or other obstacle in the warpshed, the backward pressure thus put upon the reed readily overcomes the opposing pressure of this spring, the reed-confiner rolls backward, and the reed is wholly released from its seat, remaining hanging loosely upon the warp shed; but if the reed properly seated in its place is carried by the beatingup motion of the lay substantially beyond the point where it must meet a shuttle, if one is accidentally lying in the warp-shed, then the reed is locked in place in order that it may properly beat up the weft-thread by means which I will now describe.

The letters g denote reed-confiner locks which are simply pins having some back-andforth motion, being loosely held in openings in the cross-piece d, prepared for their reception, and for the most of the time held out of contact with the reed-confiner by means of the springs h, the said pins being allowed playbetween the bunter t" and the reed-confiner e., the spring 7L bearing against the crosspiece d at one end and the head of the pin at the other to retract the coniiner-locks. -J ust as the reed is about to beat up aweft-thread into its place, as a part of the piece of cloth that is being woven, these recd-confiner locks strike the bunters t' and are thereby forced forward into the sockets e in the reed-coniner. In such position they lock the reed firmly in its place to accomplish its normal and proper beating-up function, the springs k permitting the necessary beating-up motion of the lay, but holding the reed locked in place nevertheless. Vhen the reed retreats in the backward motion of the lay and the locks g cease to have contact with the bunters i, the reed-conliner is unlocked and remains unlocked until another beating-up motion of lthe lay again brings the locks g into contact with the bunters c'.

The bunters i have just been spoken of as though they were practically rigid and stationary. As a matter of fact they rest against springs la, which are considerably stouter (that is, resist compression with greater degrec) than the lock-springs h, so that the action so far described will take place if everything goes on as it should, but if for any reason the locks g should not properly enter the sockets e' in the beating-up motion of the lay, then these springs k will permit the bunters i' to retreat and so prevent breakage of' the parts of the loom.

It will be readily understood that the springs f, the locks g, the springs h, the bunters c',

the sockets c', and the bunter-springs k mayV be more or less in number as experience and judgment dictate.
